SPECIFICATION forming part of Letters Patent No. 278,470, dated May 29, 1883.

Application tiled February 16, 1853. (No model.)A

To all whom 'it may concern:

Be it known that I, EDWARD A. TRAPP, of' the city ot New York, in the county and State of New York, have invented a new and useful Improvement in Locomotives, of which the following specification is a i'ull, clear, and exact description. I

This inventionrelates to an attachment to the cylinders of a locomotive by which the condensed water is carried from the cylinders up to the smoke-box. In this way the water is no longer blown into the streets at the sides of the locomotive through the petcocks. At

`the same time the Water is divided into a spray in` the smoke-box and acts as a spark-arrester.

The invention consists, principally, in the combination of the locomotive-cylinders with pipes containing a check-valve, and extending from the two ends of each cylinder' to the smoke-box in front ot' the tine-sheet also, in the shape of the pipe-nozzles, all as hereinafter moreV fully set forth.

ln the accompanying drawings, Figure l is va vertical longitudinal central section of a lo-l comotive smoke-box having the saddle broken oft' to expose one of the cylinders. Fig. 2 is a vertical transverse section on Athe line .c x, Fig.

'1; Fig. 3, a detail vertical longitudinal section through myimproved cylinder attachment and Fig. 4, a top view of said attachment, showing the pipe-nozzle in section.

Similar letters of 'reference indicate corresponding parts in all the figures.

The letter A represents the boiler of a locomotive, B is the smoke-box, D D are the cylinders, a is the exhaust-pipe, b b are the boilerand d is the flue-sheet, all as customary.

c c are the petcocks, one at each end of each cylinder, for blowing 0E condensed steam. Each of these petcocks connects with a pipe, E, which leads upward and terminates in the smoke-box B, in front of the liuc-sheet d and between said fine-sheet and the exhaust-pipe c. Tlepipes E are each provided with a checkvalve, f, which permits water to iiow lout of cylinders.` At the upper end the pipes E terminate in peculiar nozzles, g.

(More clearly shown in Figs. 3 and 4.) These nozzles have a very long but narrow mouth,

thus discharging the water or steam in a wide butthin or narrow sheet.

The operation is as follows: As the piston reciprocates, the condensed water in the cylinders will be forced from eachend into one ot' the pipes E. The check-valvesf will prevent the suction created by the receding piston from drawing the water back; The water will rise in the pipes E and be eventually forcibly' discharged through nozzles g into 'the smokebogr. The discharged Water, in the form ot' spray or sheets, will be thrown up in il'ront ot' the due-sheets d. The current ot' smoke and sparks from the tlues b, entering the smokebox through thetlue-sheet, willstrike thespray from the pipes E at or about at right angles, both currents will commingle, the water from the cylinders will be evaporated by the sparks, while the latter will be extinguished by the spray. In this way the pipes E serve as well as sparkarresters as vehicles for taking the waterY from the cylinders.

l claim as my invention- 1. The combination, in cylinders D with the pipesE E, having checkvalvesf, and extending from the ends ot' the cylinders'to the specitie'd.

2. The combination, in a locomotive, ot' the cylinders D with the pipes E, which terminate in front ot' the flue-sheet d, all being so arranged that the current intercepted by the current from the llues b,

smoke-box, substantially as` a locomotive, ot' the substantially as and for the purpose specified. 4

3. The combination, in a locomotive, of the pipes E, terminating in front ofthe line-sheet d, with the nozzles g, said nozzles having a long and narrow mouth to discharge water in a spray in front of said as herein specified.
